All five were treated at an area hospital and released. Four of the troopers received minor injuries and a fifth was struck by gunfire but saved by his ballistic vest.

The name of the suspect has not yet been released although authorities say he was known to law enforcement and reportedly had a criminal past.

The OHP tactical team was assisting in the service of a drug-related felony warrant around 6 a.m. Friday in downtown Talihina when the suspect opened fire with what authorities believe to be a full-automatic weapon. Troopers returned fire. The suspect was killed at the scene.

Investigators were still on scene Monday to reconstruct the scene, sift through debris, clear any other possible unsafe devices and locate the suspect's body. OHP said once they reach the suspect's remains, the Medical Examiner's Office will then identify the body and additional details will be released once available.

OHP Capt. Paul Timmons told reporters on Friday that the suspect is believed to have "booby trapped" the building with an explosive device, which is what ignited the residence and neighboring buildings. Two buildings were completely lost to the fire with others reported damaged. The downtown area and two blocks of Second Street remain closed off to the public. Downtown is expected to reopen on Wednesday, if not sooner.
